Hirose FunctionMAX FX18 Series Straight Surface PCB Socket, 140-Contact, 2 Row, 0.8 mm Pitch, Solder Termination

Hirose FX18-140S-0.8SV10 FunctionMAX FX18 Series Straight Surface PCB Socket is a precision 140-contact, 2-row board-to-board connector with a 0.8 mm pitch, designed for high-speed data transmission and reliable electrical performance. Rated at 100 V and 12 A, this surface-mount socket combines durability with advanced multifunctional contact design for industrial and electronic applications.

The FunctionMAX FX18 Series offers connectors optimized for coplanar, vertical, and stacking mating styles supporting transmission speeds up to 10 Gbit/s and PCI-Express Ver. 2.0 compatibility. The advanced contact system features ground contacts adjacent to differential pair contacts to reduce crosstalk, power contacts capable of 3 A each for dedicated power paths, and 3-step sequential contacts providing grounding and detection capabilities.

This socket has a polyamide resin housing that ensures mechanical stability and high thermal resistance. Its straight orientation and 10 mm stacking height facilitate versatile PCB designs. The gold-plated bronze female contacts enhance conductivity and resist corrosion. Additionally, six through-hole pins improve PCB retention and mechanical robustness, minimizing wrenching effects during assembly.

Operating reliably in environments ranging from -55°C to 85°C, the FunctionMAX FX18 socket is ideal for medical devices, industrial controllers and motors, data servers, smart metering systems, base station transceivers, and programmable logic controllers (PLCs). It is manufactured in Malaysia under stringent quality controls ensuring consistent performance in challenging industrial environments.

Supports high-speed transmission exceeding 10 Gbit/s. Advanced multifunctional contact design reduces noise and crosstalk. Power contacts support up to 3 A per pin, reducing signal pin count. Polyamide resin housing provides durability and heat resistance.

Surface mount with straight orientation simplifies PCB layout. Wide temperature range from -55°C to 85°C for versatile applications. Six through-hole pins for enhanced PCB retention and mechanical strength. Designed for industry standards with no certifications stated.
